Selena Gomez's Instagram was swiftly taken down on Monday after several nude photos of Justin Bieber were posted on her account.

Gomez was hacked, Variety has confirmed, but she has since re-secured her account. Variety has reached out to her rep for comment.

Gomez's Instagram was back online minutes after it was taken down, with the nude photos deleted. The singer is the most-followed person on the social media platform, with 125 million followers.

The Bieber images were the same ones that were published after the pop star's Bora Bora vacation in 2015. Gomez and Bieber used to be a couple, but are no longer together.

Bieber has said that the publication of the images, originally in the New York Daily News censored (though the uncensored versions later made the rounds online), made him feel "super violated." "Like, I feel like I can't step outside and feel like I can go outside naked," he told Access Hollywood in 2015. "Like, you should feel comfortable in your own space … especially that far away."

Gomez and Bieber have a long history together, dating back to when rumors first circulated of their romance in 2010. They confirmed their relationship in 2011, when they appeared at the Vanity Fair Oscars party together, but subsequently broke up. Their relationship had been on-again off-again ever since, though they haven't publicly dated for at least the past year.
